BELL- RINGER.

Specification of Letters Patent. Patented Sept. 19, 1911.

Application filed September 16, 1910. Serial No. 582,346.

To all whom it may concern:

Be it known that I, FRANK Simon's, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Bell-Ringers, of which thefollowing is a specification.

This invention consists of an improved pressure bell ringer designed forautomatically starting and continually ringing any bell to which it maybe attached, and is particularly adapted for use upon railwaylocomotives, fire engines, ships, light-houses, and in signal-boxes.

The apparatus may, 3150, be successfully employed to actuate whistlevalves and other similar contrivances.

In the accompanying drawings 'lnll'lllllig' art of this specification,in which like numrs of reference denote like parts wherever they occur,Figure l is a view in full elevation, illustrating the device attachedto the bell frame of a locomotive; Fig. 2 is a side view of same; Fig.-3 is-a sectional view, on an enlarged scale, on the line 3 3, Fig. 2,showing the piston in its normal position to hold the inlet valve open;Fig. 4 is a similar sectional view showing the piston in position toallow the inlet valve to close and the motive fluid to exhaust from thecyliiv der; Fig. 5 is a side elevation of the crank that is attached tothe gudgeon of the bell; Fig. 6 is a sectional view on the line (P-(3,Fig. 4; Figs. 7 and 8 are detailed views of the adjustable anddetachable bracket which retains the ringing device upon the bell frame;Figs. 9 and 10 are detailed views of the adjustable and detachable pinwhich is attached to the crank; Figs. 11 and 12 are detailed views of analternate form ofinenns for connecting the crank with the piston; andFigs. 13 and 14 are detailed views of the adjustable and detachable pinwhich is used in connection with the crank depicted in Figs. 1] and 12.

The cylinder 1 bears a rug :5 that is pivotally attached to lugs 3 ofbracket. 4 by means of pin 5 and, also, a pair of lugs 6 that isfastened to lugs 7 of bracket 4 by bolts 8, or the like, said bracketbeing secured to the frame of the bell 10 by means of a U-bolt or clamp11 and nuts 12, which, when loosened on said bolt 11, allow said bracketto be raised or lowered as may be desired: To adjust the position ofcylinder 1 relative to bracket 4 washers, or the like (not shown in. thedrawings}, can be placed between lugs 6 and? in or er to hold saidcylinder farther away from said bracket.

A screw-threaded opening 13 is formed in one end of cylinder 1 andexhaust ports 14 are formed in the side of said 0 linder. Ascrew-threaded valve casing 15 fits into. the inner end of opening 13and contains a passage 16, which communicates with said opening and theinterior of cylinder 1. The valve-stem 17 of valve 18 is adapted toslide reciprocatively in passage 16 of valve-casing 15 and is providedwith a flattened side 19, which allows the motive fluid to pass fromopening 13 into the interior of cylinder 1, when ,valve 18 is not inengagement with seat 20. Said valve-stem projects from passage 16 intothe interior of cylinder 1 and rests upon the inner end of piston 21,when the latter reaches the end of its inward stroke in said cylinder,with the result that valve 18 is held outof engagement with seat 20 inorder to allow the motive fluid to enter the interior of said. cylinder.Piston 21 norg0 molly occupies the position depicted in Fig.

3, so that valve-stem l'i' rests thereon and holds valve 18 out ofengagement with seat 20, but, when the motive fluid enters the interiorof cylinder 1, said piston is forced 35 away from valve-stem 17 to theposition depicted in Fig. 4-, whereby-valve 18 is allowed to move intoengagemeiit with seat 20 and the motive fluid within said cylinder isallowed to exhaust through ports 1-1. The outer end of opening 13 isclosed by means of a scrcw-tln'cuded plug 22 that contains a chamber 23,into which valve 18 protrudes, when said valve is held out'of engagementwith seat 20, as hereinabove described. An aperture A extends fromopening 13 to an opening 25, which is preferably screwthrondc l toreceive a pipe 26, and discharges the motive fluid from said pipe intoopening 13. Said pipe 26 conducts compressed air, steam, or other motivefluid to aperture 2 1, and, when the ringing device is used upon a ylocomotive, said pipe is connected either with the air-compressor or theboiler and the admission of the motive fluid is governed by 1 a valve inthe cab of the locomotive (not shown in the drawings).

The piston 21 is reciprocativel mounted in cylinder 1 and is providedwit ordinary packing r1ngs27. The inner end of piston 11* .21 contains achamber 28 one end of which is preferably screwthreaded internally to.

receive a screw-threaded plug 29. Apertures 30 are formed in plug i andare orranged to allow chamber is to oon'nnunicatc ith the interior ofcylimler l.

1, same fills chamber and, also. the interior of said cylinder andexerts its prcssure against the inner end ol piston 21,:

thereby forcing said piston-outwnrdly until the. exhaust ports ll areuncovered. soon 'as piston 21 uncovers the exhaust ports ll,

the valve 18 moves against seat :20 and the motive fluid within cylinderl discharges remains at rest.

through said exhaust ports, whereupon the motive fluid within chamber 28will flow into the interior of said cylinder. The piston 21 is thenmoved inwardly, in the manner hereinafter described, and the motivefiuid that remains within cylinder 1 is compressed by the inwardmovement of said iston and is forced through apertures 30 into chamber28. Thus the inward stroke of piston 21 is cushionedand the valve-stem17- is prevented. from receiving an im act too suddenly from the end ofsaid pisto 1.

A screw-threaded projection 31 bornefby the outer end of piston 21extends through an. opening in member 32 and receives a nut. 33-01 othersuitable means to secure said ;:member to said piston. A U-shaped rod 3%partly encircles cylinder 1 and preferably extends longitudinallythereof, so as to pass through openings in guide lugs 35 borne by saidcylinder. The ends of rod 34 extend through openings in member 32 andare secured to said member by means of nuts 36, or the like, so that,when piston 21 reci rocates within cylinder 1, said rod moves with saidpiston. The middle part of rod 34 bears a member 37 to which one end ofa chain 38, or the like, is attached, and the other end of said chain isfastened to member 39 that is loosely mounted on a pin or bolt 40. Pin40 is fastened in slot 41 in crank 42 by the nut 43 and is provided withflattened sides 44, which fit closely to the sides of slot 11 in orderto prevent said pin from turning in said slot. \Vh'en nut 4.3 is

loosened on pin 40,- the latter can be ad- 'usted in slot 4-1 so thatthe rock-arm can e lengthened or shortened. Crank 42 is fastened to thegudgeon 45 of hell 10 by set-screw '46. The chain 38 is preferablyformed with such length that same holds rod 34 in osition to maintainpiston 21 at the end 0 its inward stroke, when bell 10 In order tofacilitate the starting of the bell 10 automatically, the crank 42 issecured in such position to the udgeon 45 as to cause same normally toincline from a. vertical line passing through the center of said udgeonand, when motive downwardly as hereinabove described, rod

\Yhcn the 'lnolive fluid enters the Interior of cvlinder l piston andpull said crank to one side, thereby rocking bell l0 and obviating thenecessity of using a hell ropc to start the bell ringing. The length ol'chain 38 is sullicicnt lo allow the cylinder 1 to he clamped low enoughto allow the member 39 to rotate .ast member 37, in case th momentum ofwell 10 causes same to make complete revolution when rod 341 is at theend of its upward stroke.

in the altcrfmue form of connection he tween the rod 34 and crank 42, asdepicted in Figs. 11 and 12, the chain 38 is omitted entirely and amember l7 is substituted therefor. One end of pin 40 extends through aslot -18 in member 47 and bears a washer 49 that held in place by meansof a cotter 50, or the like, in order to prevent said memher fromslipping oil said pin. One end of member 47 bears a hook 51, whichpasses through an opening in member 37, and, when rod 34 is pulleddownwardly as hereinabove described, the member 47 moves downwardly withsame and pulls crank 42 to one side, thereby rocking bell 10. The slot48 allmw the pin 40 to slide therein while the bell is rwizking afterthe motive fluid cut oil.

Compressed air, steam, or other motive fluid is admitted into opening 13from the source of supply, thence passes downwardl through pussagelllinto the interior of cy inder 1 and. not only fills chamber 28, butfills the interior of the head of said cylinder, thereby exerting itspressure against the end of piston 21 and forcing said pistondowndownward mow-uncut of piston 21 causes rod 34 and chain 38 to movedownwardly and to pull crank 42 to one side or the other, wherebygudgeon 4.5 is rocked and bell 10 caused to ring. \Vhernthe pistonQlreaches the limit of its downward stroke, 11. 6., when the motive fluidwithin cylinder 1 exhausts supply of motive fluid to force valve 18against seat 20, with the result; thatthc Bdmission of motive fluid intot 1e interior of pressure by the seating of valve 18 upon seat 20 in theinterior of cylinder Lallows' ,posites1deof the centerf'of g? so Theoperation of the device as follows;

Valve l8 is clos d as before, when piston llreaches the end of its downward stroke, and allows the hell 10 toreturn, causing crank .42 to pull said piston upwardly. Crank 42 isrocked over the center of gudgeon '15, the valve 18 reopened, and thecycle is repeated until the motive tluid is shut oil. \Vhen piston itreaches the end of its downward stroke and valve 18 closes, the motivetiuid within cylinder 1 exhausts through ports 1%, whereupon the motiveliuid contained within chamber 28 will flow into the interior ofcylinder 1 and, while said piston moves upwardly, the motive fluid iscom pressed within said cylinder and forced through apertures 30 backinto chamber 28, thereby cushioning the upward stroke of piston :21 andpreventing the end of stem 17 from receiving an impact too suddenly fromplug 29.
